Abstract
. An adjustable mechanism can be used to adjust the beam shape, beam numerical aperture, beam focus depth, and/or beam size to affect the treatment depth and or the character of the resulting lesions. The system may be designed to be switchable between a treatment mode that is semi-ablative and a treatment mode that is not semi-ablative. Adjustment of these parameters can improve the efficiency and efficacy of treatment. Illustrative examples of adjustable mechanisms include a set of spacers of different lengths, a rotatable turret with lens elements of different focal distances, an optical zoom lens, and a mechanical adjustment apparatus for adjusting the spacing between two optical lens elements.
